Description

  The present invention relates to a packaging sheet containing a sheet-like food between an outer film and an inner film, a horizontally long packaged rice lump packaged by the packaging sheet, and a package of the packaged rice lump to unpack the sheet-like food. It is related with the method of winding around.

FIG. 11 shows a conventional packaging sheet (1) and rice cake (6) for this kind of packaged rice cake. FIG. 12 is an exploded view of the packaging sheet (1).
The outer film (2) of the packaging sheet (1) is a single rectangular film. The inner film (3) is formed in the same size as the outer film (2) by overlapping the inner ends of the first film piece (34) and the second film piece (35). On the second film piece (35) which is longer than the first film piece (34), a rectangular auxiliary film (36) is stacked perpendicular to the longitudinal direction of the outer film (2). Both ends of the auxiliary film (36) protrude greatly from the first film piece (34).
The outer film (2) has a portion (7) that can be divided by a cut tape (71) near the outer end of the inner film (3) on the first film piece (34) side.
The outer film (2), the inner film (3) and the auxiliary film (36) are welded and connected so as not to interfere with the sheet-like food (4) accommodated between the outer film (2) and the inner film (3). Yes.

  As shown in FIG. 11, a horizontally long stick-shaped rice cake (6) is placed on the auxiliary film (36), and both ends of the auxiliary film (36) are protruded from the end portions (37) and (37) of the end face of the stick-shaped rice cake (6). Then, the packaging sheet (1) is wound around the peripheral surface of the bar-shaped rice cake (6), and the winding end is fastened with a label (not shown).

To eat the stick-shaped rice cake (6), remove the cut tape (7) of the outer film (2), cut off the outer film (2), peel off the label, and package as shown in FIGS. Expand sheet (1).
Next, as shown in FIG. 14, the outer film dividing side end of the packaging sheet (1) is pulled to separate a part of the outer film (2) and the first film piece (34) of the inner film (3). .
From the space between the outer film (2) and the second film piece (35), the sheet-like food (4) is pulled out and wound around the stick-shaped rice cake (6).

The packaging sheet (1) must be provided with a severable portion (7) on the outer film (2), and the number of steps for producing the packaging sheet is increased accordingly. The process of unpacking is increased, which takes time.
Moreover, after unpacking, the exposed end of the sheet-like food (4) must be pulled out by hand and wrapped around the stick-shaped rice cake (6), which is difficult to carry out on the developed packaging sheet. The rice cake (6) may be dropped from the packaging sheet.
Also, if the label is peeled off before separating the separable part (7) and the packaging sheet is developed, the separable part (7) side of the packaging sheet becomes free. The separable part (7) on which the mass (6) is placed cannot be segmented. For this reason, taking out the sheet-like food (4) and winding it around the stick-shaped rice lump (6) is a troublesome work, and the possibility of dropping the stick-shaped food lump (6) from the top of the hand increases.
Furthermore, since the auxiliary film (36) is put on the second film piece (35) of the inner film (3), the film between the stick-shaped rice cake (6) and the sheet-like food (4) is in this part. Becomes double, isted, and increases the amount of film used. Moreover, in the manufacturing process of the packaging sheet, the outer film (2) and the second film piece (35) must be welded and the second film piece (35) and the auxiliary film (36) must be welded in separate processes. The packaging sheet manufacturing process becomes complicated.

  The present invention eliminates the need to provide a severable portion on the outer film, simplifies the manufacturing process of the packaging sheet, simplifies the procedure for unpacking, and allows the sheet-like food to be placed on the unwrapped packaging sheet. A packaging sheet that can be easily wrapped around a stick-shaped rice cake, a packaged rice cake packaged with the packaging sheet, and a method for winding a sheet-like food around the rice cake are clarified.

  The packaging sheet (1) according to claim 1 is a packaging sheet containing sheet-like food between the outer film (2) and the inner film (3), and the outer film (2) is one piece and is divided. There is no pre-schedulable part, and the inner film (3) is formed by overlapping the first and second rectangular film pieces (31) and (32) on the inner ends of the first and second films. The film piece (31) covers the outer film (2) leaving one end of the outer film (2), and the second film piece (32) is the outer film (2) covered by the first film piece (31). The sheet-like food (4) is accommodated between the outer film (2) and the first film (31) and protrudes from the inner end of the first film piece. 3) The first film piece (32) of the sheet-like food (4) is simply bent by the packaging sheet (1) so that the overlapping part (30) of the first film piece (31) and the second film piece (32) opens. Appearance from As long as the portion (4a) can be exposed outside the packaging sheet, the overlapping portion (30) of the first film piece (31) and the second film piece (32) of the inner film (3) can be opened, The outer film (2) and the inner film (3) are welded.

  A second aspect of the present invention is the packaging sheet (1) of the first aspect, wherein the second film piece (32) covers the end face of the stick-shaped rice cake to be packaged by protruding from both side edges in the longitudinal direction of the outer film (2). Possible protrusions (33) and (33) are provided.

  A third aspect of the present invention is the packaging sheet of the first aspect, wherein the auxiliary film (36) is formed on the second film piece (32) so as to form a T-shape with each of the first film piece (31) and the outer film (2). The protrusions (37) and (37) protruding from both side edges along the longitudinal direction of the outer film (2) of the auxiliary film (36) are in a state where there is room for the end face of the stick-shaped rice (6) to be wrapped The size can be covered.

  The packaged rice lump according to claim 4 is a stick-shaped rice lump (6) with protruding portions (33), (33), (37), (37) from the outer film (2) of the packaging sheet (1) according to claim 2 or 3 The packaging sheet (1) is wound around the peripheral surface of the stick-shaped rice lump (6).

  A method for wrapping a sheet-like food around a stick-shaped rice lump according to claim 5 is obtained by developing the packaging sheet of the packaged rice lump according to any one of claims 1 to 3 from a wrapping end and a first film of an inner film (3). The outer film (2) is bent in the vicinity of the overlapping portion (30) so that the overlapping portion (30) of the piece (31) and the second film piece (32) opens, and the first film piece (31) and The projecting end (4a) from the first film piece (31) of the sheet-like food (4) is exposed to the outside of the packaging sheet from the opening between the second film piece (32) and the outer film (2 ) Is returned to a flat state so that the protruding end (4a) of the sheet-like food (4) is positioned outside the packaging sheet, and the stick-shaped rice cake (6) on the second film piece (32) is placed on the sheet. The protruding end (4a) is moved onto the protruding end (4a) of the food (4), and the protruding end (4a) is attached to the peripheral surface of the rod-shaped rice lump (6).
